I need to access a serial device in my VirtualBox guest (Windows XP). My host system is ArchLinux 64-bit. I configured the VirtualBox serial port as follows:
- Port: COM1
- IRQ: 4
- I/O Port: 0x3F8
- Port Path:
/dev/ttyS0
Now, I am pretty certain it is /dev/ttyS0
as when I do a cat
or echo
to/from the device, I get nothing. Whereas, with the other paths, I get input/output errors.
I don't believe it is a permissions issue as I belong to the uucp group which is the owning group of the device.
Any ideas what I can try?
